It's been like this for a while actually. It seems like the signature console is broken. Like, there are the little buttons to add pictures, hyperlinks, wrap HTML around text, etc. (like you can see when posting a thread/reply), but for some reason, the buttons do not work in the signature console. They work perfectly when posting a thread or reply. I don't know whether it has something to do with my browser or not, but I was hoping someone could shed a little light onto the situation.
Thanks!
